TCP实现的客户端键盘输入数据存储到服务器端文件中

包装输出流，这样就可以一行一行的读取；
输入流关联键盘输入，就不用创建Scanner类，再进行录入了；

客户端：
import java.io.*;
import java.net.Socket;

public class TCPClient {
    public static void main(String[] args) throws IOException {
   
        Socket sk = new Socket("192.168.10.103",6666);
        OutputStream out = sk.getOutputStream();
        //包装输出流；
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(out));
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String line =null;
        System.out.println("请输入发送的消息：");
        while ((line=br.readLine())!=null){
            bw.write(line);
            bw.newLine();
            bw.flush();
            if (line.equals("bye")){
                break;
            }
        }
        sk.close();

    }
}
服务端：
import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;

public class TCPServer {
    public static void main(String[] args) throws IOException {
        ServerSocket ss = new ServerSocket(6666);
        System.out.println("服务器正常开启！");
        //侦听客户端，连接传入之前处于阻塞状态；
        Socket sk = ss.accept();
        InputStream in = sk.getInputStream();
        //包装输入流；
        BufferedReader br = new BufferedReader(new InputStreamReader(in));
        BufferedWriter bw = new BufferedWriter(new FileWriter("Msg.txt"));
        String line=null;
        while ((line=br.readLine())!=null){
            System.out.println("来消息了："+line);
            bw.write(line);
            bw.newLine();
            bw.flush();
            if (line.equals("bye")){
                break;
            }

        }
        ss.close();

    }
}
